Embodiment 1

[0035] Study on the Effects of Different Formulas of Foodstuffs on the Survival Rate of Young Larvae of M.

[0036] In late April, the young shoots of Eagle tea that had germinated and grown for 45-50 days were picked in Meitan County, Guizhou Province as raw materials, withered for 24 hours, kneaded for 120 minutes, fermented at 25°C for 600 minutes, dried at 50°C and crushed, and passed through a 60-mesh sieve. Fermented eagle tea powder; take the commercially available traditional eagle tea, dry it, pulverize it, and pass through a 60-mesh sieve to get the traditional type eagle tea powder; grind corn and soybeans, pass through a 60-mesh sieve respectively, and prepare rice oyster according to the formula in Table 1 As for the food for young larvae of borers, put the food for young larvae that has been mixed and prepared in a container, and take it out after steam sterilization at 121° C. and a pressure of 0.1 MPa for 40 minutes.

Embodiment 2

[0050] Study on the Effects of Diet with Different Moisture Content on the Survival Rate of Young Larvae of M.

[0051] Put 30 adults of the rice borer into an insect raising tank (10 cm in diameter and 20 cm in height), cover the top of the insect raising tank with 100-mesh nylon gauze, place the insect raising tank upside down in a clean container, and shake it gently to obtain eggs. With fermented eagle tea powder, corn flour and potato flour mass ratio in embodiment 1, the food material that is 7: 1: 2 is carried out to cultivating the larvae of the rice stem borer: 200 grains of gained worm eggs are put into 200g food material, and food material is set Water content is 15%, 20%, 25% three treatments. To be hatched and cultivated until the larva head width is about 1.2mm, reaching the 3rd instar larvae, record the number of 3rd instar larvae in each treatment, calculate the survival rate (%) of the young instar larvae, and repeat 5 times for each treatment.

Embodiment 3

[0060] Study on the Influence of Staged Cultivation of Tea-producing Insects on the Yield of Insect Tea

[0061] The preparation of food for the young larvae (1-2 instars) of the rice borer: the young shoots of eagle tea that have germinated and grown for 45-50 days in spring are used as raw materials, withered for 24 hours, kneaded for 120 minutes, fermented at 25°C for 600 minutes, dried at 50°C over a slow fire, and crushed , through a 60-mesh sieve to obtain fermented eagle tea powder; then crush the corn and soybeans, pass through a 60-mesh sieve respectively, and prepare the food for young larvae according to the ratio of fermented eagle tea powder, corn flour and soybean flour in a ratio of 7:1:2.

[0062] Foodstuffs for the old larvae of the rice moth (3-5 instars): traditional eagle tea fragments that have been sieved through a 120-wire sieve.

[0063] The food of the above-mentioned young larvae and senior larvae of the rice moth was packed in a container, steam ster...

Abstract

The invention discloses a sectional production method of Litsea coreana insect tea, and belongs to the technical field of insect tea production. The method comprises the following steps: dispersing eggs of a tea-producing insect aglossa dimidiata in a low-age larva foodstuff for culturing; after 3-instar larvae are obtained, continuously culturing the larvae with advanced-age larva foodstuff; after the tea-producing insects begin to emerge, collecting larva excrement, and removing impurities to obtain the litsea coreana insect tea. The low-age larva foodstuff is obtained by taking young eagle tea shoots as raw materials, fermenting, drying and crushing to obtain eagle tea powder, and then mixing the eagle tea powder with corn flour and soybean flour; wherein the foodstuff for the elderly larvae is litsea coreana fragments; and the water content of the low-age larva foodstuff and the water content of the high-age larva foodstuff are both 20 wt%. According to the method, the insect tea is obtained by improving the foodstuff of the larvae of the tea-producing insects, strictly controlling the water content of the foodstuff and carrying out segmented culture on the larvae, so that the survival rate of the tea-producing insects is effectively improved, the tea sand particles of the obtained insect tea are uniform, and the quality is improved.

Description

technical field [0001] The invention belongs to the technical field of worm tea production, and in particular relates to a segmented production method of eagle tea worm tea. Background technique [0002] Insect tea is processed from the excrement of specific host insects that eat specific host plants. It is a unique forestry insect product in the mountainous areas of Hunan, Guangxi and Guizhou in my country. As a unique "non-tea tea", insect tea has a long history of drinking in my country, and is also very popular in Southeast Asia such as Singapore, Malaysia, Nansha and other places, and has become a famous brand of special tea traditionally exported in my country . Studies have shown that insect tea is rich in high-quality high-quality protein, crude fiber, mineral elements, amino acids and other nutrients. Cancer cell apoptosis and inhibition of MCF-7 human breast cell growth have certain effects. In addition, crude polyphenols (KMICP) in chrysanthemum tea can completel...
